Using the Document Table

Note: Make sure that the document is flat against the glass surface so that the image is properly focused. Also be sure to close the document cover to prevent interference from external light.

CAUTION:

Always keep the document table clean. See Chapter 3 for information on cleaning the scanner.

Avoid twisting the document cover when you open or close it.

Do not leave photographic paper face down on the document table for an extended period of time because it may stick to the glass.

Do not apply too much pressure on the document table; excessive pressure could break the glass.

Using the Scanner

2-9

Preparing Scanner Software

For the scanner to operate, it must interact with the computer using various settings for scanning and image data transfer. Therefore, to use the scanner you need a software utility program that enables your computer to communicate with the scanner. To purchase the proper software for your scanner, consult your Epson dealer.

Using Application Software

The main advantage of using an image scanner is that you can edit the scanned images on a computer. Various software packages are available for creating and editing images. Some software packages allow you to scan images directly. Others require a utility program

to scan the image and then convert it to a usable file format.

Your software may have an installation or setup procedure that lets

you select scanner types from a list of input devices. If the ES-300C is not listed, contact your software manufacturer to see if there is a software update.

Note: The number and type of scanner functions you can use depends on your software. See your software manual for details

on available functions.

Programming

If you are an experienced programmer or are familiar with programming languages, you may be interested in the programmer’s manual which is available from your dealer. It fully describes software control of the scanner. This manual explains the formats and functions of the scanner commands and handshaking method, as well as some programming tips for getting the best performance out of your scanner.

Using the Scanner Functions

Numerous image processing functions are built into the ES-300C and many can be combined to produce a variety of effects.

Note:

Do not use DIP switch settings or the control panel to control

scanner functions unless you are using the direct print function (see Appendix D).

With some scanner software, not all of the scanner functions

may be available or the range of settings may be limited. When using application software, see its documentation for details.

Because each image, CRT, and printer combination creates a

unique scanning scenario, it is recommended that you use your scanner software to experiment with a variety of functions and settings to achieve the output you like best.

ES-300C functions and tips on how to achieve the best results using your scanner are covered in this chapter. The

Scanner Image Samples

booklet illustrates some of the effects you can create with these image processing functions. See your software manual for details on using these functions.

Epson Color Image

Output Resolution

The output resolution determines how many pixels, or dots, are used for reproducing an image. Resolution is measured in units of dpi (dots per inch) and can be selected independently for the horizontal scan and vertical scan. The ES-300C offers 19 settings: 50, 72, 75, 80, 90, 100, 120, 144, 150, 160, 180, 200, 240, 300, 320, 360, 400, 480, and 600 dpi.

Note: Use your software to control the zoom and brightness

settings unless you are using the direct print function.

(See Appendix D). Software control settings have priority over those made from the control panel, and the current settings are shown on the display.

Zoom

Use the zoom function to reduce or enlarge the size of the output image. The zoom value can range from 50% to 200% in increments of 1%. Use the software to set the horizontal scan and vertical scan values independently; when the values are different, the display shows only the larger of the two values.

Brightness

There are seven brightness levels for scanning images, ranging from

-3 (lightest) to 3 (darkest) with 0 (the default) as the normal setting. Use darker settings for faint original images, line art, and text

characters. Use lighter settings for dark original images. You can combine the brightness function with all other functions.

Using the Scanner

2-13

Using the Scanner Functions

Scanning Area

Use this function to scan a specific portion of the original image. You can choose a rectangular area anywhere within the maximum scanning area of the scanner as determined by the current resolution

and zoom settings.

Data Format

The data format determines how many bits are used to represent a pixel. A pixel (picture element) is the tiniest area a scanner “reads.” The number of bits/pixel (from 1 to 8 bits/pixel/color) determines how many colors or how many shades of gray the scanned image data can represent. The larger the number of bits per pixel, the

greater the number of shades of gray can be represented. In

monochrome (black and white) scanning, for example, a data format

of 8 bits/pixel can represent up to 256 shades of gray.

Color Mode

The color mode specifies either color scanning or monochrome

(black and white) scanning. In color scanning, you can choose either page sequence mode or line sequence mode. In monochrome scanning you can specify a dropout color, as discussed below.

Color page sequence mode

Use this mode when you don’t require the color correction function. The carriage scans the document table three times, once for each color: green, then red, then blue.

Color line sequence mode

Use this mode when you require the color correction function to achieve more accurate color. The carriage makes only one pass, reading each of the three colors for each line.

2-14

Using the Scanner

Using

Monochrome mode (standard) Use

this mode when you want to scan a black and white image. If

the Scanner Functions

you scan a color image in monochrome, you may need to specify a dropout color to recover or delete detail. See Dropout color below. Standard monochrome scanning uses all three lamps so that the

original image is scanned with white light, thus minimizing the

dropout color.

Dropout color (monochrome scanning only)

Use this mode when you scan a color image in monochrome and

you need to recover detail, eliminate background color, or eliminate

unwanted detail. Dropout color is the color that is not recognized by

the scanner. You can choose either green, red, or blue, depending on the colors on the original images.

Halftoning Mode

Halftoning is a digital process which simulates continuous gray tones or continuous colors. Some printers, however, cannot print

these continuous tones. Halftoning is suitable for original images, such as photographs, that have continuous tones. Use halftoning if your output device can reproduce only 1 to 2 bits/pixel/color image data.

Note:

Avoid changing the size of a halftoning processed image with your application software. Use the scanner’s zoom function instead to select the desired image size.

You can enable or disable the halftoning process itself, and select

from the three halftoning modes, A, B, or C.

Using the Scanner

2-15

Using the Scanner Functions

Halftoning mode A

Use this mode for scanning most images with continuous tones.

This mode produces higher contrast images than mode B. Available for 1 and 2 bits/pixel/color data in all color mode settings.

Halftoning mode B

Use this mode for images that contain large areas of similar tones. The image is converted to soft tones to blend each tone into the next. Available for 1 bit/pixel/color data. This mode is not effective

when

color line sequence is selected.

Halftoning mode C

Using mode C may produce better results if you print your image on a dot matrix printer. The image is represented in a similar way to

the images in newspaper printing; the gradations in the original image are represented by clusters of different numbers of dots. Available for 1 bit/pixel/color data. Mode C is not effective when color line sequence is selected.

Gamma Correction

Gamma correction helps you make the image you print or display

on your computer screen more closely resemble the original image

you are scanning. Use your scanner software to choose from five settings including

three general printer types and two CRT display types. You can

combine gamma correction with all other scanner functions. When

Tips on Using the Scanner

This section provides you with some tips and further information for using the scanner.

Note: Use these guidelines and your scanner software to obtain

better results when scanning and reproducing images.

Scanning Line Art and Characters

If the line art contains many straight lines, adjust the document position so that lines are aligned with the horizontal scan or vertical scan directions. If it is placed askew, the straight lines will have jagged edges.

Adjusting for Different Document Types

Focusing

For the best focus, place the document flat against the document table. As the distance from the document table increases, the focus is lost and the image is blurred or darkened.

Document surface

For better scanning results, make sure the document surface is smooth. If there is a pasted-up area, colors may blur at the edge of this area. Textured and embossed surfaces may produce blurred images because light from the scanner lamps is not evenly reflected on them.

2-18

Using the Scanner

Tips on Using the Scanner

Transparent document

Transparent material may not be scanned properly because the ES-300C scanner scans an image by reflecting light off the document surface. In the case of overhead projector transparencies, if you can clearly recognize the image on a transparency by placing it on an opaque surface, it can be scanned. Film negatives or 35 mm slides cannot be scanned because the images on them are too dark and too small for the scanner to recognize.

Thin materials

When the document paper is too thin, the image on the reverse side

of the page or on the next sheet of paper may appear as a ghost-like image superimposing the desired image. If this “bleed” occurs, photocopy the image on a heavier bond paper and rescan the image.

Minimizing

the

Moiré Pattern

A moiré pattern is the repeating interference pattern that appears overlapping a scanned image. This usually occurs with printed material processed with screens and when the pitch of the screen interferes with that of the scanner’s sensor. Moiré does not occur with ordinary photographs because they do not cause interference.

Although a moiré pattern does not occur often, once it occurs it is difficult to remove completely. To minimize the effect of the moiré pattern, you may try the following:

Place a transparent plastic sheet between the document and the document table so that the document is slightly out of focus.

Place the document slightly angled or move its position slightly.

Consult your software manual for other solutions.

Using the Scanner 2-19

Tips on Using the Scanner

The Scanning Speed

As the amount of image data increases, the time to scan the image and transfer the image data increases. The amount of image data increases as you increase the resolution, data format, zoom, and scanning area.

The speed is also affected by the interface transfer speed, computer performance, and software performance.

Different colored dots appear scattered on a background.

In monochrome scanning, the image is too faint or certain colors are fainter than other colors.

The image does not

Solution

This is normal when halftoning is selected. Halftoning simulates subtle differences of tones and luminosity of the original image with a number of bi-level dots. When the image is viewed from a suitable distance, it appears to be a similar color to your original.

If you selected standard monochrome scanning (no dropout color) using the scanner software, switch to monochrome and specify a dropout color. Then try different dropout colors until the image improves.

Check the installation and settings of your scanner software.

an IBM compatible computer. You connect the scanner using the

bidirectional parallel connector on the back panel of the scanner.

The scanner’s bidirectional parallel interface requires a compatible type of interface on your computer. If you have an IBM compatible

computer, you must install the optional bidirectional interface board

in the computer. To install the bidirectional parallel interface board in your

computer, follow the instructions in your computer’s documentation for installing optional interface boards (or cards).

Note: If you have an IBM PS/2™ computer, you can connect the scanner directly to its bidirectional parallel printer interface with a suitable shielded cable.

Setting Jumpers on the Bidirectional Parallel Interface Board

The bidirectional parallel interface board is specifically designed to connect the Epson ES-300C scanner to an IBM compatible computer. This board provides scanner control capability through bidirectional input and output, allowing the high speed transmission of data.

Two sets of jumper pins are located on the board. These jumpers allow you to configure the parallel interface port.

The Parallel Interface Cable

The parallel interface cable can be the same type as the one used for

a printer connection. The computer end of the cable must be a DB-25 (D-sub 25-pin) female plug, and the scanner end must be a 36-pin Centronics® type connector.

Connecting the Parallel Interface

Check that you have the correct parallel cable for the interface.

Make sure that both the scanner and computer are turned off.

Identifying a Cable Problem

If you are using a standard parallel interface cable, the scanner may not work properly even though the same cable works properly with a parallel printer. For example, if the fluorescent lamps come on but the scanner does not start, or if your software does not recognize the scanner, the wiring of the parallel cable may be incorrect.

Introducing the SCSI Interface

The SCSI board included in the kit allows you to connect the ES-300C scanner to an Apple Macintosh computer using the industry-standard set of hardware and software specifications known as the Small Computer System Interface (SCSI).

This fast, simple interface was pioneered by Shugart and Associates and was originally called the Shugart Associates System Interface (SASI). The American National Standards Institute modified and added to the SASI specifications and renamed it SCSI. This interface has undergone several revisions and is currently defined by ANSI specifications X3.131-1986.

The SCSI interface allows you to connect up to eight devices, including the computer, in what is called a All devices connected through the interface are assigned a SCSI ID number so that they can recognize each other. When you use multiple SCSI devices, you need to pay attention to the terminators that affect the arrangement of the devices along the SCSI daisy chain. SCSI IDS and terminators are explained in more detail in the following sections.

daisy chain

arrangement.

Setting the SCSI ID

The factory set SCSI ID of the scanner’s SCSI board is 2. The computer is always ID number 7. You must assign any other devices

a unique ID number between 0 and 6. If you are going to add the scanner to a system in which SCSI ID of 2, you must change the ID number of either that device

or the SCSI board.

Using the SCSI Interface

CAUTION:

Do not set the SCSI ID (the rotary switch) to 8 or 9.

These numbers are not available for SCSI connection.

Do not set the ID number to an ID that is already

assigned to another device. If two or more devices have the same ID number, the computer, the scanner, and/or the other device will not function properly.

Setting Up the Terminators

For SCSI devices to communicate properly with each other, the SCSI interface requires special resistor packs known as terminators. These terminators are needed to reduce the echo, standing waves, and interference along the SCSI interface.

You must be aware of the following important points about terminators before you connect your scanner to the SCSI interface.

You must have only two terminators on a SCSI daisy chain: one on the first and one on the last SCSI device.

Terminators may be internal or external. Internal terminators are

built into the SCSI device. External terminators are purchased

separately and are installed on the SCSI device. If your Macintosh has a hard disk, the hard disk is the first SCSI

device on the daisy chain. A Macintosh with an internal hard disk always has an internal terminator. A Macintosh with an external hard disk may have either an internal or external terminator.

The scanner has an internal terminator so it must be the last SCSI device on the daisy chain.

Installing the SCSI Interface Board

You install the SCSI board into the option board slot located on the back panel of the scanner as described below.

CAUTION:

To connect the ES-300C in the middle of a daisy chain, you must have the terminator resistors removed from the SCSI board by your dealer before installing the board in the scanner.

Turn off the scanner and disconnect the power cable and any

other interface cables connected to the scanner.

WARNING:

Always turn off the power and disconnect the power cable before installing or removing an optional interface board,

Connecting the Scanner to the SCSI Interface

This section shows you how to connect the ES-300C to the SCSI interface. Consult your dealer to obtain the proper SCSI interface cable.

CAUTION:

If you have a Macintosh Plus, you must first set DIP switches SW1-1, SW1-2, and SW1-3 on your scanner to on. (See pages D-4 to D-7 for information on

how to change DIP switch settings.)

Connecting the Scanner as a Single SCSI Device

The simplest connection hooks the computer directly to the scanner. To connect the scanner to the Macintosh, you need a 25-pin to 50-pin SCSI system cable.

Check that both the scanner and the Macintosh are turned off and unplugged from the power source.

Connect the 25-pin end of the cable to the SCSI port on the Macintosh. The SCSI port is the larger port with the diamond-

shaped icon over it. Be sure that the cable is securely connected.

Connect the 50-pin end of the cable to the upper connector on the SCSI board.

Connect the power cables on both the computer and scanner.

Plug the cables into electrical outlets.

Always turn on the scanner first; then start the computer.

CAUTION:

follow those guidelines could cause damage to or interfere with operation of the scanner and/or computer.

You must place the scanner (containing the SCSI board with an

internal terminator) at the end of the daisy chain. The order of

connection does not affect the speed of scanning operations.

If you have a Macintosh with an internal hard disk, the hard disk itself has a terminator and therefore is the first SCSI device in the daisy chain.

Attach any SCSI devices (without terminators or with terminator resistors removed by your dealer) to the middle of the chain as shown in the following illustration.

Remember that you must place the scanner (with its built-in terminator) last on the daisy chain.

CAUTION:

If you want to place the scanner in the middle of the SCSI chain, you must take your SCSI board to the dealer to have the terminator resistors removed. If you have already installed the SCSI board, see the section on removing the SCSI board later in this appendix. If you choose to place the scanner in the middle of the SCSI chain, you may need additional cables. Consult your dealer.

The Power on Sequence

SCSI devices with terminators (the first and last devices in the daisy chain) must be turned on before the Macintosh to allow information to pass through the SCSI interface. The Macintosh may not start up if these devices are not turned on. SCSI devices in the middle of the chain may be left off if you don’t plan to use them at this time.

If you have an internal hard disk, turn on the scanner and any other SCSI devices you plan to use. Wait a few seconds; then turn on the computer.

If you have an external hard disk, turn on the scanner, external hard disk (first on the daisy chain), and any other SCSI devices you plan to use. Wait a few seconds; then turn on the computer.

About Direct Print

The direct print function allows you to use your ES-300C scanner as a color copier if you have an Epson LQ-2500, LQ-2550, or LQ-860 printer with a color ribbon or an HP PaintJet or HP3630 color graphics printer with a parallel interface. With direct print, you connect the scanner directly to your printer and print the scanned image in color. Consult your dealer to obtain the special parallel

interface cable required for the direct print function.

Choosing a Printer

You can use the direct print function only through the parallel

interface of the scanner. You select your printer through the DIP

switches as explained in the following section.
